Treehouse of Horror IV

In the wraparound, Bart introduces each of the three segments by walking through a gallery of paintings and each time choosing one of them as the focus of his story.

In "The Devil and Homer Simpson", Homer sells his soul to the devil, who takes the form of Ned Flanders, for a donut. After Marge and Lisa plead with Ned, he agrees to put Homer on trial. At the trial, Marge saves Homer from being sent to Hell by displaying a photo from their wedding day. On the back of the photo, Homer has written that, in return for Marge giving him her hand in marriage, he pledges his soul to her forever; therefore, it was not his property to sell at the time of his deal with Ned. The case is dismissed, and Ned frees Homer, but Ned gets his revenge by turning Homer's head into a donut.

In "Terror at 5+1⁄2 Feet", Bart tries to warn the passengers on the school bus that a gremlin is loosening the lug nuts on one of the wheels, but nobody can see the gremlin. In desperation, Bart climbs halfway out the window to scare off the gremlin with an emergency flare. As Bart is pulled back into the bus by Principal Skinner and Groundskeeper Willie, he drops the flare on the gremlin, who catches fire and falls from the bus, but is found by Ned. Even though everyone sees the damage when they make it to school, Bart is sent to a psychiatric hospital for his disruptive behavior. Bart is relieved as he is finally able to rest, but is once again petrified when the gremlin appears in the back window of the ambulance, holding Ned's severed head.
